The history of the jade, or green Guianan stones, is intimately linked with that of the warlike women named Amazons by sixteenth-century travelers. La Condamine has produced many testimonies in favor of this tradition. Since returning from the Orinoco and Amazon I have often been asked in Paris if I agreed with that learned man, or thought that he said what he said to satisfy a public eager for novelties. A taste for the marvelous and a wish to describe the New World with some of the tones of antiquity no doubt contributed to the reputation of the Amazons. But this is not enough to reject a tradition shared by many isolated tribes. I would conclude that women, tired of the state of slavery in which men have held them, united together and kept their independence as warriors. They received visits once a year from men, and probably killed off their male babies. This society of women may have been quite powerful in one part of Guiana. But such is the disposition of man's mind that, in the long succession of travelers discovering and writing about the marvels of the New World, each one readily declared that he had seen what earlier ones had announced.
